本文件规定了ISO 5053-1中定义的回转越野可变范围卡车和越野可变范围卡车（以下简称卡车）及其工作平台的安全要求，这些工作平台具有可打开的前防护装置，以便移除车顶材料（以下简称工作平台）。 本文件涉及与卡车和综合工作平台组合相关的重大危险、危险情况和事件，当其按预期使用时，以及在制造商可合理预见的误用条件下。本文件涵盖的重大危险列于附录A中。 注1:在卡车封闭驾驶室的操作位置，在特定情况下也可提供回转上部结构、动臂和工作平台运动的双重控制装置。 本文件不涉及可能发生的危险: a） 使用非整体式工作平台或其他非设计用于起吊人员的附件时； b） 搬运可自由摆动的悬挂式工作平台时； c） 在地下或潜在爆炸性环境中作业时； d） 在清除石棉时，考虑到纤维的可能释放。 本文件未规定配备工作平台的卡车的安全要求- 高空进入。 注2:工地的国家法规可适用于石棉清除，以涵盖可能释放纤维的相关风险。

This document specifies the safety requirements for slewing rough-terrain variable-reach trucks and rough-terrain variable-reach trucks defined by ISO 5053-1 (hereafter referred to as trucks) and their work platforms having front guards that can be opened for removal of roof material (hereafter referred to as work platforms). This document deals with the significant hazards, hazardous situations and events relevant to the combination of the truck and the integrated work platform when it is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. The significant hazards covered by this document are listed in Annex A. NOTE 1 Duplicate controls for the slewing upper structure, the boom and the work platform movements can be also provided under specific circumstances at the operating position in the enclosed cab of the truck. This document does not address hazards which can occur: a) when using non-integrated work platforms or other attachments not designed for lifting persons; b) when handling suspended work platforms which can swing freely; c) when operating underground or in potentially explosive atmospheres; d) when removing asbestos, regarding the possible release of fibres. This document does not specify safety requirements for trucks equipped with work platforms intended for leaving and re-entering at height. NOTE 2 National regulations for worksites can apply for asbestos removal to cover the risks related to the possible release of fibres.
